>>13890252He's right. If you realize that gravity isn't actually a force, but a curvature of space, then objects in space which are in orbit are actually going in straight lines, which become curved from our perspective due to extradimensional fuckery.
If you consider that gravity is all around us and constantly subjected to minute waves from black hole collisions millions of light years away, then it is impossible to have something completely straight in all dimensions.
